Abstract
Abstract
In this study, we examined the physical characteristics of two local breeds (Cemani chicken and Mojosari putih duck) and two imported breeds (White Leghorn chicken and Peking duck). A total of 280 eggs were tested. Egg physical characteristics and hatchability were analyzed using ANOVA with consideration for breed effects using GLM (SPSS version 25). Peking ducks have a heavier, larger mean of geometric diameter, larger volumes, and larger surface area of eggs (p<0.05). Among them, the Cemani chicken is the smallest in the world (p<0.05). Cemani chicken and Mojosari putih ducks had the highest sphericity and shape index scores, and were significantly different from White Leghorn chickens and Peking ducks (p<0.05). Density parameters were highest in Cemani chickens as well as in White Leghorn chickens, but were significantly different from Peking ducks and Mojosari putih ducks (p<0.05). Hatchability was related to the shape index value. Mojosari putih ducks and Cemani chickens have a higher shape index than White Leghorn chickens and Peking ducks. In summary, the Peking duck was better, but the hatchability was higher for the Mojosari putih duck and Cemani chicken.
